Description

Technical Field

[0001] The invention relates to the technical field of silica gel key manufacturing, in particular to a device for manufacturing silica gel key using waste materials. Background Art

[0002] Silicone is a common raw material for keypad production. It is widely used because of its excellent heat resistance, cold resistance, environmental resistance, electrical insulation and fatigue resistance. The production and processing of silicone keypads is based on the actual requirements of the quality and specifications of the silicone keypads to determine the hardness and performance of the rubber material. After the rubber is prepared according to the formula, it is produced according to the specifications to finally obtain the required product.

[0003] Currently, when manufacturing silicone keys, the keys need to be pressurized in a closed mold cavity to form a product. However, after molding, the silicone easily sticks to the lower mold, making it difficult to remove the molded keys. Therefore, they need to be peeled off manually. However, due to the residual heat left during the molding process, workers can easily burn their hands, resulting in the inability to remove the molded keys immediately after molding. As a result, the next molding cannot be continued. A certain amount of time must be waited for the product to cool naturally before molding can be continued, thereby reducing the molding work efficiency. Summary of the Invention
